I don't know what is wrong with my code..it says there is a problem evaluating the lenght()

the error is when evaluating the length against the counter

script.js 
var temperatures = [100,90,99,80,70,65,30,10];
var i =0;
while( i< temperatures.length()){
  console.log(temperatures[i]);
  i++;
}

Hi!

it seems you have a couple of parentheses after length. Try removing them!

while( i < temperatures.length ){
  console.log(temperatures[i]);
  i++;
}

Here's an explanation of why: Why does the length function in javascript not have parentheses?
